APPARATUS FOR CO-IVIPRESSING PEAT, PULP, Sac., I NTO BLOCKS.

SPECIFIGATXON forming part of Letters Patent N 0. 684,967, dated October 22, 1901.

Application filed April 9 1901. Serial NO- 55,064. (No model.)

To @ZZ whom, t may concern:

Be it known that I, JAMES WEsrAWAY, engineer, a subject of the King of Great Britain residing at No. 6 Dowgate Hill, Cannon streef,

in the city of London, England, have invented certain new and useful Improvements in or Connected with Apparatus for Compressing Peat, Pulp, or other Material into Blocks or other` Forms, of which the following is a specixo fication.

of is to improve the construction of the pressure-chamber of such apparatus for facilitating the escape of expressed fluid.

The following is a description of the present invention with reference to the accom- 2o panying drawings, in Which- Figure lis an elevation of a pressure-chamber constructed in accordance with the present invention. Fig. 2 is a vertical section thereof through the line X X of Fig. 3. Fig.

3 is a transverse section through the line Y Y of Fig. 1. Figs. 4 and 5 are ldetached views of grooved drainage-plates which are arranged between the central disks of wood and outside those disks of wood which constitute either 3o end of the series; and Fig. 6 is a cross-section through the line Z Z, Fig. 5.

The same letters of reference indicate like parts in all the figures.

In carrying the invention into effect a cy- 3 5 lindrical or tubular pressure-chamber ct is employed, made up of two or more flanged sections connected together by bolts a passing through the danges a and provided between the flanges with a packing b, of Wood, cut

4o with the grain on end, or of other suitable filtering material, and one end of this pressurechamber is open,while the other end is, with the exception of one or more escape-orifices for fluid, closed, by preference, by means of a cap or cover a3, removably secured in position by any suitable means. Within the chamber and abutting against the cap a3 a coiled spring c may be arranged, and beyond the spring c and bearing against the same is a 5o disk or piston dii, which tightly its the cylinder a and is on its inner face provided with drainage-grooves. 4A closely-fitting disk c, of wood, cut with the grain on end, or of other suitable filtering materiahis placed upon said drainage-plate, and a quantity f of the material to be treated is then filled into the chamber. Another disk of wood or other filtering material e is placed thereon, and another drainage-plate d is placed on said disk, and the chamber a may be further charged in the same manner. A plunger g, actuated by hydraulic or other power, is now caused to act upon the last plate d* of the grooved plate d and compress the material f against the action of the spring c, which becomes thereby compressed, the air or other fluid expressed therefrom passing away by the disks e, the grooves of the drainage-plates d d* dtl, and the packing Z) between the fianges a. When the compression has been completed, the last one, di, of the drainage-plates may be fixed in its then position by means of set-screws a4 or otherwise and the pressure afterward maintained by the compressedspring, leaving the plunger free to be employed upon another charge in a separate chamber.

To withdraw the charge, the cap a3 is removed, when the whole contents of the chamber a may be forced out.

If desired, the spring c may be dispensed with and the first drainage-plate dit* made to take a bearing against the cap as;

The grooves in the drainage-plates cl d* dl* may be made as shown at Fig. 4, or they may be arranged radially, as illustrated at Fig. 5.-

The periphery of each disk is, by preference, beveled, as shown at Fig. 6.

The end plates d* dit* are only grooved on their inner faces, as shown at Fig. 2.

By the means hereinbefore described various materials may be effectually compressed and the contained iiuid expressed therefrom,

.more especially as the pressure may be by JAMES WEsTAWAY.
